Not sure I like that. It would also be good to point to the concerns that people have with the routing.Routing interface. This makes the tests look a little less nice unless we let the topology solely operate on RoutingDHT's.

fixes #929

What's this change? Was it not building before? Or is it a merge conflict?

Maybe you can wrap the dhts when you create them above

Would you let the topology operate on Routing DHTs?

We should debate whether this actually belongs in Boxo, for example here

Just thinking about how best to decouple the Routing adapter

Can we avoid accessing the host field on the DHT (and the Peerstore method)? Places where we do that are candidates for useful methods to expose on the DHT type, for example: Connectedness(), PeerInfo(), ID(), Addrs(), AddAddrs()

Same for accessing .kad - these could be methods on the DHT type that delegate to kad.

These aren't essential for this PR but something to think about as we evolve the usability of this implementation.
